Hi, guys, I''m learning to use Rails, and, while reading the "Rails: Up And Running" book, I tried to make an insertion validation, using the following code: class Photo < ActiveRecord::Base validates_presence_of :filename end It simply didn''t work, the validation does nothing and an insertion with an empty field returns TRUE. What''s wrong? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Oops, sorry George, indeed I should have put some more information
about what''s happening and what''s the scene here...
There''s a table in the db called "photos", with two columns,
"id" and
"filename". "filename" is set for "NULL" as
default, but I want to use
"validates_presence_of" as a mean to verify the field entry on the
console ("script/console").
When I do a "photo=Photo.new", and a "photo.save", in the
console, it
should return "false", and generate the error strings for future
analisys, but it''s returning "true" and it creates a new
record in my
db with the "filename" field empty.
This was not supposed to happen because of
"validate_presence_of :filename", which I wrote in the
"photo.rb"
model file.
Do I need to put more information? Thanks a lot, George!
Diogo

Hi, George, Can''t understand. Yesterday it was returning "true" in the console, with empty field, and today, after I answered your message for the first time, I tested it again, and it''s returning "false"!!! I tried to restart the server, and nothing, and, just now that I restarted my computer, it''s working! What''s happening? Any clue? Thanks, George, again!

Hi, where''s the code where you''re trying to save the instance to the database? This should be somewhere in your controller code. Also, can you provide your script/console transcript similar to what George provided?
